In 1897, Kate married Henry Wischhusen. The marriage was registered in Edmonton, Middlesex. 
In 1911, Kate and Henry were living in Wood Green, Middlesex. The couple had five daughters and one son. 
Kate passed away in 1956. Her death was registered in Edmonton, Middlesex. 
All the children that have had birth registrations listed so far indicate Alice's last name at birth was Haynes. Also, I have not located a marriage for an Alice Lucy, bu rather located a reference that matches the 1901 and 1911 census for Henry Wischhusen and it indicates her name was Kate.
